摘要:

针对碳纤维复合材料(CFRP),分别开展在干钻和超声干钻条件下PCD刀具制孔试验研究,探求改进碳纤维复合材料切削性能的方法,进一步提高CFRP的制孔效率和质量。在干钻和超声干钻条件下,分别采用PCD常规刀具和PCD织构刀具对碳纤维复合材料进行制孔,对不同条件下产生的切削力、孔入口直径尺寸、孔外部形貌及刀具表面黏结情况进行分析。在超声干钻条件下,纤维丝断裂更加充分,但孔直径总体偏大,相对于PCD常规刀具,PCD织构刀具制孔使总切削力最高降低34.72%,孔径相对误差降最大降低1.27%。在PCD织构刀具加工条件下,孔入口处表面质量更好,超声干钻使得总切削力降低6.64%~16.87%。相较于干钻制孔,超声干钻断屑效果更好,能有效抑制入口处毛刺的产生。在超声干钻条件下,相较于PCD常规刀具,PCD织构刀具可以有效降低切削力。在PCD织构刀具条件下,相较于干钻制孔,超声干钻可以有效降低切削力。

Abstract:

An experimental study was conducted on the hole⁃making performance of carbon fiber⁃reinforced composites (CFRP) using a PCD tool under dry drilling and ultrasonic dry drilling conditions. The objective was to identify potential avenues for enhancing the cutting performance of CFRP and to optimize the efficiency and quality of hole⁃making for CFRP. In order to ascertain the efficacy of PCD conventional tools and PCD weaving tools in the context of dry drilling and ultrasonic dry drilling conditions, the holes were made in CFRP. The cutting force, hole entrance diameter size, hole external morphology, and tool surface adhesion were analyzed under different conditions. In the context of ultrasonic dry drilling, the fiber filaments were found to be more extensively broken, although the resulting hole diameter was typically large. Compared to the PCD conventional tool, the PCD structuring tool resulted in a reduction by 34.72% in the total cutting force and by 1.27 % in the relative error drop of the hole diameter. The surface quality at the entrance of the hole was superior under the PCD textile tool machining conditions, and ultrasonic dry drilling reduced the total cutting forces by 6.64% to 16.87 %. Compared to dry drilling, ultrasonic dry drilling generated a more pronounced effect on breaking up chips and could effectively inhibiting the generation of burrs at the entrance. In the context of ultrasonic dry drilling, PCD weaving tools could reduce the cutting force in comparison with conventional PCD tools. Similarly, when using PCD weaving tools, the cutting force could be effectively reduced compared to dry drilling.
